Question

Solve C = AB + D for B.

Answer 1

you have to get by on its own. Any idea how? where to start?

Answer 2

nop

Answer 3

i'd start by subtracting d and putting it on the other side

Answer 4

then proceed to divide the whole thing by a

Answer 5

that should get you b on its own

Answer 6

you want to isolate B

\(C=AB+D\)

first step would be to get rid of D
it is +D so the opposite is -D
\(C-D=AB\)
Next divide A since AB is A*B and you need the opposite
\(\dfrac{C-D}{A}=B\)

Answer 7

subtract d from both sides, then divide by a, it should look like this \[\frac{ C-D }{ A }=B\]
Hope this helped

Answer 9

C = AB + D
1) Subtract D on both sides to leave AB alone because the goal is to get B:

C-D=AB

2) Divide A since it is being multiplied to B on both sides to cancel A on the right where the AB is.

(C-D)/A = B
B= C-D/A
